Description

Technical Field

[0001] The invention relates to a dishwasher. Background Art

[0002] Generally, the bowl baskets used to hold dishes and bowls in dishwashers are fixed, and a spray arm is also provided inside the dishwasher to spray water toward the bowl basket. The spray arm rotates so that the water flows from all directions to wash the dishes and bowls in the bowl basket, thereby achieving the purpose of cleaning. However, in this type of rinsing, because the angle between the rinsing water flow and the tableware is fixed, there are always areas that the rinsing water flow cannot directly spray, which affects the cleaning effect.

[0003] In order to solve this problem, the Chinese utility model patent with patent number CN201920788385.0 (publication number CN210541431U) discloses a "rotating dishwasher with a bowl basket", which includes a chassis, a cleaning part for cleaning kitchenware in the bowl basket, a cleaning tank, a circumferential interval of the bowl basket, and a first spray part for spraying gas to the push plate to drive the bowl basket to rotate. During washing, the cleaning part rinses the kitchenware in the bowl basket, and at the same time, the first spray part is started to spray gas toward the push plate. The reaction force generated by the multiple push plates under the impact of the gas drives the entire bowl basket to rotate, so as to achieve the purpose of washing the kitchenware while pushing the bowl basket to rotate, so that the cleaning part can wash the kitchenware from all angles as the bowl basket rotates, avoiding dead corners, cleaning more thoroughly, and having better cleaning effect.

[0004] However, after the dishes are placed on the bowl basket, the overall weight is very heavy. If the bowl basket is rotated as a whole, a large amount of energy is required. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a dishwasher which can reduce the cleaning dead angle of kitchen utensils and has low energy consumption in view of the current status of the prior art.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: a dishwasher, comprising

[0007] Box, open on one side;

[0008] A bowl basket, open at the top and located in the box;

[0009] A spray arm, on which a plurality of spray holes facing the bowl basket are provided, and the spray arm is located in the box body;

[0010] It is characterized by that it also includes

[0011] A receiving box, on which a hollow drain hole is provided, the receiving box is located in the bowl basket, and the receiving box can rotate around an axis extending horizontally or vertically, and the receiving box is located on the spray path of some spray holes;

[0012] The driving mechanism is drivingly connected to the accommodating box.

[0013] Preferably, there is a gap between the receiving box and at least one of the side walls of the bowl basket as a placement area for placing tableware, and the placement area is at least partially located on the flow path of the water drained from the drain hole. In this way, during the rotation of the receiving box, it is also equivalent to a spray part, and the water flowing out of the drain hole of the receiving box will clean the kitchen utensils in the bowl basket, reducing the cleaning dead corners of the kitchen utensils in the bowl basket.

[0014] In order to facilitate the placement of kitchen utensils in the bowl basket and the storage box, the bowl basket can enter or move out of the box from the opening of the box. When the kitchen utensils need to be placed, the bowl basket is pulled out of the box. When the kitchen utensils need to be washed, the bowl basket is pushed back into the box.

[0015] In order to prevent the driving mechanism from affecting the movement of the bowl basket, a power output member is provided in the box body, and a power input member connected to the accommodating box is provided on the accommodating box. The power output member is detachably connected to the power input member, and the power input member and the power output member constitute a driving mechanism for driving the accommodating box to rotate.

[0016] The box body may be open at the top or open at the front, the rotation axis of the accommodating box extends along the front-to-back direction, and the power output member is installed at the rear of the box body.

[0017] In order to rotatably arrange the accommodating box in the bowl basket, support frames are provided on the front and rear sides of the accommodating box in the bowl basket, and support rods that can be correspondingly supported on the support frames are provided on the front side wall and the rear side wall of the accommodating box. The support rods extend in the front and rear directions, and the distance between the accommodating box and the bottom wall of the bowl basket can meet the rotation of the accommodating box around the support rods. The axis of the support rods is the rotation axis of the accommodating box, and the support rods located on the rear side serve as a power input member.

[0018] In order to connect the power input member and the power output member detachably, a joint is provided on the support rod at the rear side, and the power output member is provided with an interface with an open front side facing the joint, and the joint can be detachably inserted into the interface, and in this state, the joint and the interface are relatively fixed in the circumferential direction;

[0019] Alternatively, the support rod at the rear side is provided with an interface with an open rear side, and the power output member is provided with a joint facing the interface. The joint can be detachably inserted into the interface, and in this state, the joint and the interface are relatively fixed in the circumferential direction.

[0020] In order to enable the joint and the interface to be circumferentially limited in the inserted state, a limiting groove connected to the interface is provided on the wall surface of the interface, and a limiting block that can be detachably inserted in the limiting groove is provided on the circumferential wall of the joint.

[0021] The containing box can be used to place unbreakable tableware, such as plastic soup spoons, plastic bowls and plates, etc., and can also be used to hold cloth kitchen utensils.

[0022] In order to improve the cleaning effect of cloth kitchen utensils, the inner wall surface of the accommodating box is provided with a convex column for striking the cloth kitchen utensils. In this way, during the rotation of the accommodating box, the cloth kitchen utensils are struck against these convex columns by centrifugal force, forming a hammering effect similar to hand washing, so that the cloth kitchen utensils can be washed more cleanly. The free end of the convex column can be designed to be smooth to prevent the cloth kitchen utensils from being entangled on the convex column.

[0023] Preferably, a plurality of the protrusions are provided on one of the inner wall surfaces of the accommodating box. When the driving mechanism is not working, the inner wall surface of the accommodating box is its bottom wall surface. At least two of the protrusions are arranged in a row to form a limiting row. A limiting area for limiting tableware is formed between two adjacent limiting rows or between a limiting row and the side wall of the accommodating box. If there are no difficult-to-clean kitchen utensils to be cleaned, the accommodating box can be kept from rotating. Tableware of any material can be placed in the accommodating box for cleaning, making full use of the accommodating box. The limiting row also arranges and separates the tableware to improve the cleaning effect.

[0024] In the above scheme, a power output member is provided in the box body, a power input member connected to the accommodating box is provided on the accommodating box, the power output member is connected to the power input member, the power input member and the power output member constitute the driving mechanism for driving the accommodating box to rotate, and the power output member is a motor with adjustable speed.

[0025] In order to achieve a better cleaning and drying effect for cloth kitchen utensils, the dishwasher also includes a drying component capable of inputting hot air into the cabinet, and the working method of the motor is as follows:

[0026] (1) Before cleaning the cloth kitchen utensils, the motor drives the container box to rotate at a specific speed N1 at a constant speed, and the current A1 at this time is detected and recorded. Then, when the container box rotates at the speed, the spray arm sprays water, and the cloth kitchen utensils move in the container box under the action of centrifugal force to be cleaned;

[0027] (2) Dehydrating the cleaned cloth kitchen utensils. During the dehydration process, the motor drives the receiving box to rotate at a specific speed N2, where N2 is greater than or equal to N1. At this time, the cloth kitchen utensils will throw out water under the action of centrifugal force;

[0028] (3) After the dehydration setting time (e.g., 10 minutes), the motor drives the accommodating box to rotate at the initial speed N1, and detects the current A2 at this time, and compares the difference between A2 and A1. If the difference is within the set range, it is determined that the dehydration is completed and step (4) is executed. If the difference is not within the set range, the process returns to step (2);

[0029] (4) After the dehydration is completed, the motor drives the accommodating box to rotate at a constant speed N3, where N3 is less than or equal to N1. At this time, the drying component works until the cloth kitchen utensils are dried. In this way, after it is determined that the cloth kitchen utensils have been dehydrated, the drying component works to dry them, which can reduce the energy consumption of the drying component.

[0030] Compared with the prior art, the advantages of the present invention are as follows: by arranging a accommodating box in the bowl basket, the present invention can place kitchen utensils that are difficult to clean in the accommodating box. When the accommodating box rotates, the kitchen utensils placed therein have fewer cleaning dead corners and can be washed more cleanly; kitchen utensils that are easier to clean can be placed in the area of ​​the bowl basket outside the accommodating box. Compared with the method of rotating the entire bowl rack, this design method of the present invention can not only reduce the cleaning dead corners of kitchen utensils that are difficult to clean, achieve a better cleaning effect, but also have low energy consumption.

[0036] The present invention is further described in detail below with reference to the accompanying drawings.

[0037] like Figures 1 to 5 As shown, the dishwasher of this preferred embodiment includes a cabinet 1, a bowl basket 2, a spray arm 3, a receiving box 4 and a driving mechanism.

[0038] One side of the box 1 is open. In this embodiment, the front side of the box 1 is open. The top of the bowl basket 2 is open and located in the box 1. The bowl basket 2 can move forward and backward from the open part of the box 1 to enter or move out of the box 1. The method of pulling out the bowl basket 2 can adopt the existing technology and will not be repeated here. When it is necessary to take or put kitchen utensils, the bowl basket 2 is pulled out of the box 1. When it is necessary to wash the kitchen utensils, the bowl basket 2 is pushed back into the box 1. Kitchen utensils include tableware such as bowls, plates, knives, forks, spoons, chopsticks, etc., also include pots, and also include cloth kitchen utensils such as rags, scouring pads, etc.

[0039] The spray arm 3 is located in the box body 1, and is provided with a plurality of spray holes facing the bowl basket 2. In this embodiment, the spray arm 3 can be rotatable around a vertically extending axis and is located below the bowl basket 2. The spray arm 3 can adopt an existing structure.

[0040] The receiving box 4 is provided with a hollow drain hole 41, the receiving box 4 is located in the bowl basket 2, and the receiving box 4 can rotate around an axis extending horizontally or vertically. The receiving box 4 is located on the spray path of some spray holes, and the driving mechanism is connected to the receiving box 4 to drive the receiving box 4 to rotate.

[0041] Kitchen utensils that are difficult to clean and not easy to break can be placed in the accommodating box 4. When the accommodating box 4 rotates, the kitchen utensils placed therein have fewer cleaning dead corners and can be washed more cleanly; the area of ​​the bowl basket 2 outside the accommodating box 4 can be used to place kitchen utensils that are easier to clean. Compared with the method of rotating the entire bowl rack, this design method of the present invention can not only reduce the cleaning dead corners of kitchen utensils that are difficult to clean, achieve a better cleaning effect, but also reduce energy consumption.

[0042] In the bowl basket 2, support frames 5 are provided on both the front and rear sides of the accommodating box 4. The bowl frames are hollow structures composed of multiple frame bars. A buckle 51 is provided at the bottom of the support frame 5. The longitudinal section of the buckle 51 is C-shaped with an open bottom. The frame bars at the bottom of the bowl basket 2 can be detachably inserted into the buckle 51 from the opening of the buckle 51.

[0043] In this embodiment, the rotation axis of the accommodating box 4 extends in the front-to-back direction. The front side wall and the rear side wall of the accommodating box 4 are provided with support rods 6 that can be correspondingly supported on the support frame 5. The distance between the accommodating box 4 and the bottom wall of the bowl basket 2 can meet the rotation of the accommodating box 4 around the support rods 6. The support rods 6 extend in the front-to-back direction, and the axis of the support rods 6 is the rotation axis of the accommodating box 4.

[0044] A power output member 7 is provided in the box body 1 and is installed at the rear of the box body 1 . In this embodiment, the power output member 7 is a motor with adjustable speed. A sealing box 11 is provided on the rear side wall of the box body 1 and the motor is arranged in the sealing box 11 .

[0045] The accommodating box 4 is provided with a power input member connected thereto. The power input member and the power output member 7 constitute a driving mechanism for driving the accommodating box 4 to rotate. The power output member 7 is detachably connected to the power input member.

[0046] The support rod 6 at the rear side is used as a power input part, and a joint 61 is provided on the support rod 6 at the rear side. The power output part 7 is provided with an interface 71 with an open front side facing the joint 61. The joint 61 can be removably inserted into the interface 71, and when the two are inserted, the joint 61 and the interface 71 are relatively fixed in the circumferential direction. In order to allow the joint 61 and the interface 71 to be circumferentially limited in the inserted state, a limiting groove 711 connected to the interface 71 is provided on the wall surface of the interface 71, and a limiting block 611 that can be removably inserted into the limiting groove 711 is provided on the peripheral wall of the joint 61.

[0047] Of course, it is also possible that the support rod 6 located at the rear side is provided with an interface 71 with an open rear side, and the power output member 7 is provided with a connector 61 facing the interface 71, and the connector 61 can be detachably inserted into the interface 71, and when the two are inserted, the connector 61 and the interface 71 are relatively fixed in the circumferential direction.

[0048] The inner wall of the accommodating box 4 is provided with protrusions 42 for striking the cloth kitchen utensils. In this way, during the rotation of the accommodating box 4, the cloth kitchen utensils are struck against the protrusions 42 by centrifugal force, forming a hammering effect similar to hand washing, so that the cloth kitchen utensils can be washed more cleanly. The free end of the protrusion 42 can be designed to be smooth to prevent the cloth kitchen utensils from being entangled on the protrusion 42.

[0049] In addition, a plurality of bosses 42 are provided on one of the inner wall surfaces of the accommodating box 4. When the driving mechanism is not working, the inner wall surface of the accommodating box 4 is its bottom wall surface. At least two of the bosses 42 are arranged in a row to form a limiting row. A limiting area for limiting tableware is formed between two adjacent limiting rows or between the limiting row and the side wall of the accommodating box 4. If there are no difficult-to-clean kitchen utensils to be cleaned, the accommodating box 4 can be kept from rotating, and tableware of any material can be placed in the accommodating box 4 for cleaning, so that the accommodating box 4 is fully utilized, and the limiting row also arranges and separates the tableware to improve the cleaning effect.

[0050] The dishwasher also includes a drying component capable of inputting hot air into the housing 1. The drying component can adopt an existing structure, such as the drying component in "A Cleaning Machine" disclosed in the Chinese invention patent application with application number CN202310454510.5 (publication number CN116548890A).

[0051] The working method of the motor is:

[0052] (1) Before the cloth kitchen utensils are cleaned (i.e., before the spray arm 3 sprays water), the motor drives the accommodating box 4 to rotate at a specific speed N1, and the current A1 at this time is detected and recorded. Then, when the accommodating box 4 rotates at this speed, the spray arm 3 sprays water, and the cloth kitchen utensils move in the accommodating box 4 under the action of centrifugal force to be cleaned;

[0053] (2) Dehydrating the cleaned cloth kitchen utensils. During the dehydration process, the motor drives the accommodating box 4 to rotate at a specific speed N2, where N2 is greater than or equal to N1. At this time, the cloth kitchen utensils will throw out water under the action of centrifugal force;

[0054] (3) After the dehydration setting time (e.g., 10 minutes), the motor drives the accommodating box 4 to rotate at the initial speed N1, and detects the current A2 at this time, and compares the difference between A2 and A1. If the difference is within the set range, it is determined that the dehydration is completed and step (4) is executed. If the difference is not within the set range, the process returns to step (2);

[0055] (4) After the dehydration is completed, the motor drives the accommodating box 4 to rotate at a constant speed N3, where N3 is less than or equal to N1. At this time, the drying component works until the cloth kitchen utensils are dried. It can be manually checked whether the required drying degree is reached. In this way, after it is determined that the cloth kitchen utensils have been dehydrated, the drying component works to dry them, which can reduce the energy consumption of the drying component.

[0056] In this embodiment, there is a gap between the accommodating box 4 and at least one of the side walls of the bowl basket 2 as a placement area for placing tableware, and the placement area is at least partially located on the flow path of the water drained from the drain hole 41. In this way, during the rotation of the accommodating box 4, it is also equivalent to a spray part, and the water flowing out of the drain hole 41 of the accommodating box 4 will clean the kitchen utensils in the bowl basket 2, reducing the cleaning dead corners of the kitchen utensils in the bowl basket 2.

[0057] The accommodating box 4 includes a box body 43 with an open side and a cover body 44 that can open or close the opening of the box body 43. The cover body 44 can be rotatably connected to the box body 43 or detachably connected to facilitate placing kitchen utensils in the accommodating box 4.

[0058] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.
